Pathfinder 1.0 Character Sheet General Questions

Dear Roll20 Community, I am quite new to the Roll20 system and this is just my first post so I hope this is the right place for these kind of questions. I am currently doing a Pathfinder 1.0 adventure as a player and I have some questions about how to use efficiently the character sheet. In particular, I would like to know how to add temporary buffs (e.g. from spells) to only one type of my meele attacks (I am playing a Summoner Synthesist 13th level, so I have 5 natural attacks ; 4 claws and 1 bite). I would like to add the Greater Magic Fang bonus only to Claws attacks and not to the Bite but I do not know exactly how to do it with the Buffs part (I know how to increase in general all melee or ranged attacks but not single specific ones). Many thanks in advance for your help!

Have you checked if the wiki page is of any help? <a href="https://wiki.roll20.net/Pathfinder_Official" rel="nofollow">https://wiki.roll20.net/Pathfinder_Official</a>

Since it is such a situational bonus, I would just add the bonus to the notes or description section of the attack to remind you to add it if the buff is up.

Dear Andreas and Kraynic, I already tried to look carefully on the Wiki and Help pages but nothing similar to my case is in there, unfortunately. I think the option of the reminder to the attacks could be an option but I will try to see if I can find something more "automatic". I have other two questions actually... Is it possible to add Buffs to the existing natural armor (e.g. for the spell Barkskin)? I tried with "+5 to natural" but does not work since I have already 14 to natural armor. The problem applies also for the Large Eidolon evolution were I would like to add separately the +2 natural armor bonus and the -1 size penalty to armor class. I tried somehting like "+2 to natural; -1 size to armor" but does not work (even using the real sheet attribute names, e.g. ac_natural_bonus and ac_armor_bonus). Any suggestion? Do you know where I can find the list of attributes (alias) for the Armor Class field on the Buff chapter of the Pathfinder Roll20 Wiki? It seems this part is completely omitted in the guide... Thanks again!

If that isn't in the guide, then you have to wait for someone who knows the sheet to answer, or try to figure out from the sourcecode, looking ath the HTML file, and the code for the relevant section. <a href="https://github.com/Roll20/roll20-character-sheets/tree/master/Pathfinder%20by%20Roll20" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/tree/master/Pathfinder%20by%20Roll20</a> No idea how feasible it is in this case, but that's generally an option for sheet in general.

Thanks for the suggestions, I will try to contact someone from roll20 support team also because some buffs does not work even if the format is correct. I tried to add a simple "+1 to melee; +1 to meele damage" but the only one that work is the first part for the +1 to attack rolls but nothing is added to the melee damages...or better in the temp meele damage field the +1 is written but it is not added to the damage in the various attack fields as well during rolling. Someone maybe know how to contact the support team from roll20, in case?
